Also, polynomials can consist of a single term as we see in the third and fifth example. We should probably discuss the final example a little more. This really is a polynomial even it may not look like one. Another way to write the last example is. By converting the root to exponent form we see that there is a rational root in the algebraic expression.
All the exponents in the algebraic expression must be non-negative integers in order for the algebraic expression to be a polynomial. For instance, the following is a polynomial. There are lots of radicals and fractions in this algebraic expression, but the denominators of the fractions are only numbers and the radicands of each radical are only a numbers. Therefore this is a polynomial. The degree of each term in a polynomial in two variables is the sum of the exponents in each term and the degree of the polynomial is the largest such sum.
Also, the degree of the polynomial may come from terms involving only one variable. Note as well that multiple terms may have the same degree.
We can also talk about polynomials in three variables, or four variables or as many variables as we need. Next, we need to get some terminology out of the way.
For a set of data containing two or more quantitative properties, statisticians use functions to denote a relationship between two or more distinct properties. When we find a function that lies reasonably close to the collected data points, we create a trend line which says how one property behaves as a function of the other ones.
We call this curve fitting. Then we can use this to make predictions about the former property once we know something about the others. Of course, this is only possible if the two quantities are related: How many uncles a kid has got has probably nothing to do with how far they can jump.
Polynomial and rational functions are easy to work with because you only need to make use of elementary operations. Polynomial functions are very simple in form and easy to use, but they have limitations with regard to statistical modeling. They can take on only a limited number of shapes and are particularly ill-suited to modeling asymptotes. This need not be a problem. For lots of datasets, their are no asymptotes and data is more or less bounded.
Here, n and m define the degrees of the numerator and denominator, respectively, and together, they define the degree of the polynomial. Rational functions are a little more complex in form than polynomial functions, but they have an advantage in that they can take on a much greater range of shapes and can effectively model asymptotes.
They are also more accurate than polynomial functions both inside and outside the limits of collected data. However, rational functions sometimes include undesirable asymptotes that can disrupt an otherwise smooth trend line. They are also a little bit more difficult to compute, since you also need division to compute them. However, they still run fast.

Polynomials and rational functions are used for approximation in many everyday devices. For example, every time we take a picture with a smartphone, our phone looks at some data points and fills in the appropriate colors in the blanks, thus saving us a lot of memory, with the help of rational functions.
Every time we say something through the phone, our phone tries to reduce the background noise by approximating our sound for short periods of time, again with the help of rational functions.
